Abstract

We report a novel composite material of hierarchically structured Mn ₃O₄ grown on three-dimensional graphene foam (3DGF). This hierarchical Mn₃O₄/3DGF composite was fabricated as a flexible and freestanding biosensor for nonenzymatic determination of glucose and H₂O₂, significant analytes in health care and food industry. The Mn₃O₄/3DGF-based biosensor achieved high sensitivity, large linear range and low detection limit for the detection of both analytes, due to the synergistic effects of the two materials, which combines the high electrocatalytic activity of the nanostructured Mn ₃O₄ network, and high conductivity and large surface area of 3DGF. This enzymeless biosensor also exhibited excellent performance for real-time detection of glucose and H₂O₂ in serum and food samples.
